Web browsing activity visualization system for administrator assistance

In this research, we have built a system that visualizes the Web browsing activities of network users by using Kohonen´s self-organizing map (SOM). This system visualizes the Web browsing activities of an organization by making the processing object not an individual user but a user group. The network administrator can comprehend the Web browsing activities of the organization by referring to the map. This system extracts a keyword from an HTML file, and creates a browsing model that makes use of a Vector Space Model. The features of the browsing model are emphasized by weighting and after that, the model is visualized by SOM.
